Distinct Summits Climbed

This list shows the peaks climbed by Mark Lyons, with one entry for every summit attained, by whatever means. Attempts and simple hikes are not shown. Only the first ascent date is listed for peaks climbed more than once. Sortable columns of information about each peak are also provided, including elevation, location, prominence, isolation, and high point status.

The "Pers Iso" column shows the distance of a peak to the nearest higher peak also climbed. Sorting by this column will highlight the geographical diversity of the list, with peaks furthest from other higher climbed peaks showing up at the top.
